Mid-key values give Suzanne Duchamp its characteristic quietness - nothing blazes, nothing disappears. Temperature is cool-dominant, with blue and green families claiming the largest areas. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #A48247 at 27.3% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The highest-chroma note - #836B48 - appears at just 8.1%, deployed as a precision accent against the quieter ground. At 53 units across the value scale, the palette keeps contrast readable without letting it dominate. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 4 of Suzanne Duchamp's sequence - a single chapter in a chromatic story told across many works.
